4-bit Parallel-Access Shift Register IC - 74HC95 The 74HC Series 74HC95 is a 4-Bit Shift Register with serial and parallel synchronous operating modes. The serial shift right and parallel load are activated by separate clock inputs which are selected by a mode control input. The data is transferred from the serial or parallel D inputs to the Q outputs synchronous with the HIGH to LOW transition of the appropriate clock input. The HC95 is fabricated with the Schottky barrier diode process for high speed and is completely compatible with all Motorola TTL families. Pinout: Pinout Of 74HC95 IC

4-Line to 16-Line Decoder/Demultiplexer IC - 74HC154 This is the 74HC Series 74HC154 IC, Each of these 4-line-to-16-line decoders IC utilizes TTL circuitry to decode four binary-coded inputs into one of sixteen mutually exclusive outputs when both the strobe inputs, G1 and G2, are LOW. The demultiplexing function is performed by using the 4 input lines to address the output line, passing data from one of the strobe inputs with the other strobe input LOW. When either strobe input is HIGH, all outputs are HIGH. These demultiplexers are ideally suited for implementing high-performance memory decoders. All inputs are buffered and input clamping diodes are provided to minimize transmission-line effects and thereby simplify system design. check out : 74238 IC Pinout: Pinout Of 74HC154 IC

4-Pins DIP Momentary Square Tactile Push Button Switch 10 Pieces - 6x6x5mm 6x6x5mm Tactile 4 Pin Push Button Switch is widely used as a standard input buttons on electronic projects. These work best when you mount it on PCB but can also be used on a solderless breadboard for temporary connections in prototypes. The pins are normally open (disconnected) and when the button is pressed they are momentarily closed and complete the circuit. This tact switch also offers reliable dome contact technology and strong tactile feedback, with multiple operating forces to choose from. Applications include telecommunications, consumer electronics, audio/visual, medical devices, testing/instrumentation, and computer/peripherals.

4.5in Flex Sensor A SpectraSymbol Flex Sensor 4.5? Bend Sensor for Hand Gesture Recognition is a simple resistive sensor which is 4.5? in length yet a powerful sensor to sense the flexibility. As the sensor is flexed, the resistance across the sensor increases. The resistance of the flex sensor changes when the metal pads are on the outside of the bend (the text on the inside of bend). The connector is 0.1? spaced and bread board friendly. Check the datasheet for full specifications. The flex sensor is a bend detecting sensor which has got numerous applications in robotics, medical and haptic technology. The resistance of these sensors changes in accordance with the bend, which can be measured using any microcontroller. Note: The base of the sensor is sensitive to bending and may get damaged. Make sure that you bend only the sensing area. Flex Sensor Interfacing with Arduino: Flex Sensor Connection with Arduino Uno Applications: Angle Displacement Measurement Bends and Flexes physically with the motion device Possible Uses Robotics Gaming (Virtual Motion) Medical Devices Computer Peripherals Musical Instruments Physical Therapy
